Torque sensor and rotation detector

摘要

The sensor has inductive coupling units at rotor units (114a, 114b), and a coil circuit in a stator unit (120). The coil circuit has a flexible substrate on which coils are formed as conductor, and the substrate runs along a sensor region. The unit (120) has an evaluation circuit connected in the coil circuit to evaluate a signal received from one coil to determine a value for the rotary position of the rotor units. An independent claim is also included for a method for manufacturing a sensor.
